Linux VPS crash on certain player count - Dr.Einstein - 13.09.2013

This always happens when player count is 70 or higher and a player connects. Sometimes it happens on 90-ish...

Now, I know most of this stuff is gibberish.. the last 3 lines may give us something..
I did make search on this, it had something to do with no memory being available? It may also have nothing to do with the plugins, some Pawn function of something...

Re: Linux VPS crash on certain player count - sanplayer - 13.09.2013

That last 3 lines (I used to have linux vps) normally means it cannot allocate enough memory.

What plugins have you got running and what are the vps specs?

I think it is the VPS' fault... RAM is 4GBs, which is way enough for 70 players. CPU usage never goes higher than 40%.

Plugins: filemanager, irc, crashdetect, sscanf, streamer, audio

Uhm. You sure your script isn't getting overloaded? sometimes features in your script can cause too much load.

Well, what would you say would cause the overload, too many variables? I don't think that is the problem though.. no new variables are created as player connects, only modified.

How much ram is being used when the server is close to 70 players?

Looks like a RAM usage issue. I would check how much your using when you have a certain player amount.

Maybe the VPS Internet network isn't able to cope.

I don't think that could be it.

It might be the IRC message sending though, sometimes at least 5-10 lines are sent in less than 2 seconds...

PS: Would it be the CPU usage, sometimes it goes higher than 75%.. but goes back down to 20% or so.
